Quick assessment

Affected
elwerene libreoffice-convert
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Knobibrot libreoffice-convert是Knobibrot个人开发者的一款文档格式转换组件。 Knobibrot libreoffice-convert 1.8.2之前版本存在安全漏洞，该漏洞源于路径遍历，index.js使用调用者控制的options.fileName值进行路径拼接而未正确归一化，可能导致攻击者将文档缓冲区写入进程可写的任意路径，如SSH authorized_keys、cron配置或web根目录。

Vulnerability Title
libreoffice-convert: path traversal / arbitrary file write
Source: CVE Program / CVE List V5
Vulnerability Description
libreoffice-convert is a Node.js module for converting office documents to different formats. Prior to 1.8.2, index.js uses the caller-controlled options.fileName value in path.join(tempDir.name, fileName) without reducing it to a base name. A filename containing ../ can escape the temporary directory because path.basename() normalization is missing and write the supplied document buffer to an arbitrary path writable by the process, including an SSH authorized_keys file, a cron configuration, or a web root. This issue is fixed in version 1.8.2.
